Sweden-headed wastewater treatment and biogas technology providers MalmbergGruppen AB has revealed that it has via its subsidiary Malmberg Water AB, received an order for a biogas upgrading unit from Estonia-based investment company GreenGas OÜ. The unit will be installed at AS Estonian Cell's biogas plant in Kunda, Estonia and represents the first installation of a biogas-to-biomethane upgrading plant in the Baltic States for Malmberg.

The privately owned investment company, GreenGas OÜ is active in the biofuels market and has signed a long-term agreement with pulp producer Estonian Cell to buy their biogas and upgrade it to biomethane. Part of Austria-headed Heinzel Holding GmbH, AS Estonian Cell has during the last two years developed a well-functioning biogas plant at their site in Kunda, 100 km East of Tallinn, where biogas has been used together with natural gas in boilers.
With the new upgrading unit Estonian Cell can now replace some of their natural gas usage with renewable, locally produced biomethane. The amount of gas upgraded equals the gas usage by buses in Pärnu and Tartu, and this upgrading project is the first in the Baltic states.
It is remarkable that we, as a Swedish cleantech company, can contribute to lowered carbon emissions in markets around the world, and with this project also Estonia. Biomethane is a smart energy source and this project really shows the meaning and potential of the circular economy, said Erik Malmberg, CEO Malmberg Water AB.
Currently, Malmberg has supplied over 100 biogas upgrading units to 10 different countries. This will be Malmberg’s first plant in Estonia and the first in the Baltic States.
